VOA科学技术2024--US Police Try AI for Help with Crime Reports

（单词翻译）

Some police departments in the United States are experimenting with artificial intelligence (AI) tools to help them produce incident reports. Police officers who have tried the AI chatbots praise the technology as a time-saver.

Yet some government lawyers, legal experts, and others have expressed concerns about the AI-produced reports.

A "game changer"

One chatbot police are testing uses the same technology as ChatGPT. The company that sells it, Axon, is best known for developing the electroshock weapon called the Taser. It is also the leading supplier of body cameras in the U.S.

Matt Gilmore is a police officer in Oklahoma's capital, Oklahoma City. He describes the AI chatbot as a "game changer" for police work.

Recently, Gilmore and his police dog, Gunner, searched for a group of suspects for almost an hour. In the past, after completing a search, the officer would spend another 30 to 45 minutes writing up a report about the incident. But this time he used AI.

The tool considered all the sounds and radio talk recorded by the microphone attached to Gilmore's body camera. Then it produced a report.

The process took eight seconds.

"It was a better report than I could have ever written, and it was 100 percent accurate. It flowed better," Gilmore said. The report even documented an event he did not remember: Another officer identifying the color of the car from which the suspects fled.

The new AI product is called Draft One. Axon's founder¹ and CEO Rick Smith said it received the "most positive reaction" of any tool the company has offered.

"They become police officers because they want to do police work, and spending half their day doing data entry is just a tedious part of the job that they hate," Smith said.

But he also noted² legal and ethical³ concerns about the tool.

He said government lawyers prosecuting⁴ criminal cases want to be sure that police officers are responsible for writing their reports. Sometimes, officers are called to testify in court about cases they worked on.

Prosecutors⁶ "never want to get an officer on the stand who says, well, 'The AI wrote that, I didn't,'" Smith said.

AI technology concerns

AI technology is not new to police agencies. American police already use such tools to read license⁷ plates, identify suspects' faces, recognize the sounds of gunshots, and predict where crimes will happen.

In Oklahoma City, police showed the tool to local prosecutors before using it for criminal cases. The lawyers advised the police to be careful with the tool. For now, it is used only for minor⁸ incident reports that do not lead to arrests.

"So no arrests, no felonies, no violent crimes," said Oklahoma City police Captain Jason Bussert, the head of information technology for the 1,170-officer department.

Police in the city of Lafayette, Indiana, have a different policy on the new tool. Police Chief Scott Galloway told the Associated Press that officers can use Draft One for every incident. He said the tool is very popular with the city force. It began using the tool earlier this year.

Police in Fort Collins, Colorado, are also permitted to use the AI tool on any kind of report. However, the head of the force's technology department said the tool does not work well in very noisy parts of the city.

Axon will not say how many police departments are using Draft One. Other companies including Policereports.ai and Truleo offer similar tools. Experts and police officials expect AI-generated reports to become more common in the coming months and years.

Some experts and observers are calling for public discussion about the use of AI tools to write police reports. Chatbots that use AI technology are not mistake-free. Sometimes these chatbots can produce false information.

That issue worries Andrew Ferguson, a law professor at American University.

"I am concerned that automation and the ease of the technology would cause police officers to be sort of less careful with their writing," he said..

Ferguson said a police report is important in determining whether an officer's suspicion supports "someone's loss of liberty." It is sometimes the only testimony⁹ a judge sees in a court case, particularly for minor crimes known as misdemeanors.

Human-created police reports also have problems, Ferguson noted. He said it is not yet known which kind of report writer, human or AI, is more dependable .
